Abstract

CPO and its main product, namely RBD Palm Olein, are commodities that have strategic value to be developed by processing them into derivative products to increase selling value.One product that is widely used and needed by the market today that can be processed from palm oil is Mono-Diacylglycerol (MDAG) emulsifier.This study aims to determine the process of making Mono- Diacylglycerol (MDAG) by glycerolysis reaction using a lipase enzyme catalyst and to determine the best enzyme catalyst concentration.based on the characteristics and quality test of the resulting MDAG products. The stages carried out in this study began with the characterization of raw materials, the synthesis of Mono-Diacylglycerol (MDAG), product purification from catalysts, adsorbents and solvents, and tested the characteristics and quality of the products produced. In this study, the best enzyme catalyst concentration was found in the use of 6% catalyst with MDAG acquisition of 59.8%, ALB content of 0.2%, pH value at number 6, density of 0.95 gr/cm3, surface tension of 18 .65dynes/cm. And the results of the functional group test using FTIR on the resulting MDAG show thatthe functional groups contained in MDAG, namely 3R-COOR'-2OH and 3R-2COOR'-2OH were read on infrared absorption from FTIR at a wavelength of 721.38 cm-1 – 3392.79 cm-1.

Abstract

This Community Service (PkM) activity aimed to enhance the knowledge of 10th-grade students at SMAN 1 Kuok, Kampar Regency, regarding the sustainable palm oil industry, palm oil processing, and the health benefits of its derivative products, especially red palm oil. The background of the activity was the students' lack of knowledge about palm oil and its derivatives, despite living in a palm oil plantation hub. The implementation methods included a location survey and needs analysis, knowledge and technology transfer, active partner participation, interactive counseling, and evaluation through pre-test and post-test. The results showed high enthusiasm from the participants. Questionnaire-based evaluation revealed that the activity was considered highly beneficial and successfully improved students' understanding of palm oil, its derivative products, and their health benefits. It was concluded that this PkM activity was effective in increasing students' knowledge and is expected to encourage their role as agents of change in supporting the sustainable palm oil industry in their region.

Abstract

The quality of crude palm oil (CPO) is an important factor affecting the success of the refinery process, particularly during bleaching. This study aimed to evaluate the effect of CPO quality with different Deterioration of Bleachability Index (DOBI) values on the quality of refined bleached deodorized palm oil (RBDPO) at various bleaching earth dosages. Two CPO samples with DOBI values of 2.67 and 0.87 were used, while bleaching earth concentrations were varied at 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The observed parameters included carotene content, percentage of carotene reduction, absorbance value as an indicator of oil clarity, peroxide value, and percentage of peroxide value reduction. The results showed that increasing the bleaching earth dosage improved bleaching effectiveness, as indicated by decreases in carotene content, absorbance, and peroxide value in both CPO samples. CPO with a DOBI value of 2.67 exhibited greater reductions in carotene, absorbance, and peroxide value than CPO with a DOBI value of 0.87. These findings indicate that the initial quality of CPO significantly influences bleaching efficiency and the quality of refinery products.
